Abstract

Volume changes in the reactions of orthophosphoric acid neutralization with solutions of NaOH, NH4OH, and tris(hydroxymethyl)methanamine in the mixed solvent H2O-dimethylformamide were studied by dilatometric titration. Volume effects of the reaction depending on the mixed solvent composition and base strength were discussed.
